What Is Structural Waterproofing?

Structural waterproofing is the process of protecting buildings and below-ground structures from water penetration. Effective waterproofing prevents moisture entering walls, floors and foundations, helping to preserve the integrity of the building while creating dry, usable internal spaces.

Professional waterproofing is essential for:

​

  • Basements

  • Cellars

  • Underground car parks

  • Lift pits

  • Foundations

  • Retaining walls

  • Concrete structures

  • New build developments

  • ​

A properly designed and installed waterproofing system reduces the risk of damp, mould, structural deterioration and costly future repairs.

​

Type A waterproofing is often specified where groundwater protection is required for below-ground structures.
